Answer:
50
Step-by-step explanation:
(-5)* (-5) = 25; as the negatives cancel out
25 * (2) = 50; arithmetic
Answer:
The system is INCONSISTENT.
Equation of two parallel lines differ only by a constant.
Step-by-step explanation:
The given equations are:
2x + y = -11
6x + 3y = 15
From the graph we see that these lines are parallel. Any two parallel lines never meet. Hence, they do not have a solution.
Hence, the system is called an Inconsistent system.
Also, note that it can be seen easily from the equations are parallel without the help of a graph.
The equation 6x + 3y = 3(2x + y)
The terms (except for the constant term) are proportional. That means they represent parallel lines.
Hence, the answer.
( x,y ) -> y is second number
so y=9.
To help you understand this better, here are my steps.
You convert both the numbers to improper fractions- like this
5/3 multiplied by 5/4
Now, you multiply across the top and bottom
(5*5)/(3*4)
25/12
Hope this helped!
